Abstract

Adaptations for seed dispersal are found everywhere in nature. However, only a fraction of this diversity is accessible through the study of model organisms. For example, Arabidopsis seeds are released by dehiscent fruit; and although many genes required for dehiscence have been identified, the genetic basis for the vast majority of seed dispersal strategies remains understudied. Explosive fruit generate mechanical forces to launch seeds over a wide area. Recent work indicates that key innovations required for explosive dispersal lie in localised lignin deposition and precise patterns of microtubule-dependent growth in the fruit valves, rather than dehiscence zone structure. These insights come from comparative approaches, which extend the reach of developmental genetics by developing experimental tools in less well-studied species, such as the Arabidopsis relative, Cardamine hirsuta.

创造爆炸爆炸性水果的形式与功能
种子传播的适应性在自然界随处可见。然而,通过对模式生物的研究,我们只能获得这种多样性的一小部分。例如,拟南芥的种子是由开裂的果实释放出来的;虽然已经确定了许多开裂所需的基因,但绝大多数种子传播策略的遗传基础仍未得到充分研究。爆裂果实会产生机械力,将种子播撒到大面积区域。最近的研究表明,爆炸性扩散所需的关键创新在于局部木质素沉积和果瓣中微管依赖性生长的精确模式,而不是开裂区结构。这些见解来自比较方法,该方法通过在拟南芥近缘植物卡达明(Cardamine hirsuta)等研究较少的物种中开发实验工具,扩展了发育遗传学的研究范围。
